Pous de glaç or ice wells are constructions that were built be digging into the ground in areas with easy access to ice or snow. These well were made to be filled with ice and snow and thus have them available throughout the year. The top was covered with a vaulted roof which had some opening around the perimeter to allow for the insertion or extraction of snow or ice, although sometimes these had a lower entrance to remove these from below.

The ice well of Buscastell, dating from 1650, is found in an exceptional state of conservation, after the restoration process it underwent between 1997 and 2002. It was a complex process, undertaken by the History Workshop of Maçanet de la Selva, which managed to refurbish it, the tallest ice well remaining in all of Catalonia, measuring twelve metres high inside.

The ice well, belonging to the Buscatell family, is cylindrical in shape and is topped by a stone cupola twelve metres deep and eight metre in diameter. It is accessed through a lowered arched doorway at the bottom and had a hatch in the cupola through which to send the ice. At the top of the well we find all the information about the structure.
